34907A

Keysight Technologies (Agilent HP)Modules, misc.

The Keysight (formerly Agilent) 34907A is a multifunction module designed for the 34970A and 34972A Data Acquisition/Switch Units. It provides high flexibility for sensing and control applications by integrating 16 bits of digital input/output, a 100 kHz gated totalizer, and two ±12 V analog outputs (DACs) on a single earth-referenced plug-in module.
